For centuries, carp's delicate flesh has been overshadowed by its intricate network of intermuscular bones – until now. A research team led by Academician Gui Jianfang at the Chinese Academy of Sciences (CAS) announced on December 23, 2025, the successful development of 'Zhongke No. 6,' a genetically modified Gibel carp completely free of Y-shaped bones.
CRISPR Precision Meets Culinary Innovation
Using CRISPR/Cas9 gene-editing technology, scientists identified and disabled the runx2b gene responsible for bone development in early embryos. This surgical modification preserves the fish's main skeletal structure while eliminating 80+ problematic spines. The achievement follows six years of research under CAS's 'Precision Seed Design and Creation' program.
Sustainable Protein for Growing Demands
The new breed demonstrates 15% faster growth rates and 20% improved feed conversion compared to conventional carp, according to preliminary trials. Enhanced disease resistance makes it particularly suitable for high-density aquaculture systems – a critical advantage as global demand for freshwater fish protein continues rising.
Market Implications and Future Prospects
While regulatory approvals are pending, industry analysts predict this innovation could reshape Asia's $86 billion aquaculture sector. The CAS team confirms ongoing collaborations with major fisheries to scale production, potentially offering consumers bone-free carp products by late 2026.
